Title: Apparatus for winding yarn or thread
Inventor: KORITYSSKY IAKOV ILICH
IPC: B65H59/38
Filed: 1966-03-02
Abstract: 1,090,865. Driving rollers; yarn tensioning. VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY INSTITUT TEXTILNOGO I LEGKOGO MASHINOSTROENIYA. March 2, 1966. No. 9116/66. Heading DID. [Also in Division F2] Apparatus for winding yarn at constant tension comprises means for positively feeding yarn to a drum by which the yarn is wound on a spool, and means for sensing the length of yarn between the feed means and the drum, which means is operatively connected to means which brake the drum to a greater or lesser extent when the sensed length varies from a predetermined value. In Fig. 1, yarn is fed by driven rollers 1, 2 to a drum 4. This comprises a shell slip-coupled to a driving-shaft by a member keyed to the shaft and spring-urged to bear on the inner face of one of the ends of the shell. A pivoted lever 18 having a shoe bearing on the drum is connected to one end of a spring, the other end of the spring being connected to a bellows 7 inside a chamber 15. Compressed air is supplied between the bellows and the chamber walls by a pipe having a bleed nozzle 11. The length of yarn between the feed rollers and the drum is sensed by a pivoted lever 6, a predetermined value being established for the length according to the position of a weight 10. When the length departs from this value, the lever pivots so that a cam 12 at the pivot of the lever 6 closes the bleed-valve to a greater or lesser extent, so that the bellows contracts or expands, the pressure exerted by the spring on the brake-lever changes, and the degree to which the brake is applied to the drum changes correspondingly. The more the brake is applied, the more the drum slips on its driving-shaft.

Title: Improvements in shaped structures of synthetic condensation polymers and their production and use
IPC: D01F6/62
Filed: 1958-03-24
Abstract: Shaped structures having the property of spontaneous and irreversible elongation when subjected to the action of water at 90 DEG  C. are made from structures of a synthetic condensation polymer having a birefringence of at least 0.02 and a relatively low degree of crystallinity by heating the oriented structures for such a time and under such conditions that they shrink by at least 20% without attaining the maximum level of crystallinity obtainable by shrinking with water at 90 DEG  C.  Shaped structures include continuous textile filaments, staple fibres, ribbons and films.  The oriented structure can be produced by shaping the synthetic condensation polymer in the presence, or absence of solvents with simultaneous or subsequent orientation, e.g. by stretching, under conditions which do not produce a high level of crystallinity, e.g. in one or more steps. Various methods of producing the shunk structures are indicated. Thus, an oriented substantially amorphous polyethylene terephthalate filament may be placed in cold water which is then heated slowly to 85 DEG  C. to produce a shrunk but spontaneously elongatable product, or a shaped structure may be heated by passage through a zone maintained at about 90 DEG  C. (during which time shrinkage of the structure occurs) and cooled before the maximum permissible level of crystallinity is attained in said zone.  Preferably, however, the structures are passed through a zone wherein they are contacted with a fluid medium maintained at about 90 DEG  C.  The fluid medium may be water, silicone oil, Wood's alloy, steam, air or nitrogen, and the structures and the fluid medium may be passed concurrently through a nozzle.  Infra-red radiation may also be used as a heating means. Preferably the condensation polymer is a terephthalate polyester of which at least 85% by weight of the structural units have either the formula <FORM:0841230/IV(a)/1> G being a divalent organic radical containing 2-10 carbon atoms, or the formula <FORM:0841230/IV(a)/2> Thus G may take the form -CH2-Am-CH2-where m is 0 or 1 and A represents an alkylene radical or a bis-alkylene ether radical.  The linear terephthalate polyesters may be prepared by reacting terephthalic acid or an esterforming derivative thereof with a glycol of formula G(OH)2, G being defined above.  Specified glycols are ethylene glycol, diethylene glycol, butylene glycol, decamethylene glycol, and trans-bis-1 : 4-(hydroxymethyl) cyclohexane, also termed trans-p-hexahydroxylylene glycol.  Copolymers may be formed by replacing up to about 15% of the terephthalic acid or derivative thereof with another dicarboxylic acid or ester-forming derivative thereof, e.g. adipic acid, dimethyl sebacate, isophthalic acid and sodium 3 : 5-dicarboxymethoxybenzene-sulphonate.  Examples are given. Specifications 712,950, 841,228 and 841,229 are referred to.

Title: Oxidation of silicon tetrahalides
Inventor: ARKLESS KENNETH
IPC: C01B33/18
Filed: 1961-03-15
Abstract: Silicon dioxide is produced by oxidizing a vaporized silicon tetrahalide (other than silicon tetrafluoride) in a hot fluidized bed of particulate material, while maintaining the bed height and the flow rate of one or more of the reactants so that the overall oxidation reaction takes place partly in and partly above the bed. The oxidizing agent is oxygen with or without an inert gas (e.g. as air).  Heat may be supplied to the bed from an external source, e.g. by preheating the reactants, by a furnace surrounding the bed, or by heating coils in the bed.  Alternatively or in addition, a fuel which may be solid (e.g. carbon or coke) or gaseous (e.g. CO) may be introduced into the reactor.  At least 15% of the overall oxidation of silicon tetrahalide to silica is carried out above the bed.  To increase the effective flow rate, the flow rate of one or more of the reactants may be increased, or an inert gaseous diluent, e.g. N2, Cl2, or recycle effluent gas from which SiO2 has been removed, may be introduced into the bed. The silicon tetra halide may be introduced in an inert carrier gas or in a fuel gas.  The bed material may be silica, alumina, zircon or rutile of particle diameter within the range of 40 to 1000 microns, and the bed may be maintained in the range of 500 DEG  C. to 1200 DEG  C.  The product as described in an example is a very voluminous amorphous white silica having a particle diameter of 0.006 to 0.008 microns and a specific surface area of 350 m2g-1 Specifications 796,735 and 919,018 are referred to.

Title: Improvements in or relating to the manufacture of double-sided mosaic screens for television and similar tubes
IPC: H01J29/41
Filed: 1945-04-18
Abstract: 590,928. Electron image tubes. McGEE, J. D., and AMBROSE, E. J. April 18, 1945, Nos. 9649 and 12848. [Class 39 (i)] The conducting elements of a double-sided mosaic screen are secured in the interstices of the insulated metal mesh by a thin film of silica, prepared by hydrolysing a silica compound. The mesh may be of aluminium (aperture, say .002" square), which has been anodized. The conducting elements may be minute silver balls ; or particles of a fine silver powder (.0001" diameter) may be deposited by rubbing on or by settling from a suspension in water containing a wetting agent, the mesh being vibrated at audible or ultrasonic frequency to work the particles into the mesh, and the excess, brushed off. During this operation the mesh may be cemented to a glass backing plate. The silicon compound is preferably a silicon ester (e.g. ethyl orthosilicate) hydrolysable in. air, but silicon tetrachloride or other esters may be used which must be hydrolysed in the vapour of hydrochloric acid, nitric acid, or ammonia; a solution in acetone is sprayed or poured on to the mesh. If the thin layer of silica over the exposed surfaces of the elements is of too high a resistance it may be removed by buffing. A thin metal layer may be deposited over the whole mosaic, which may be sensitized either for secondary or for photoemission. After manufacture and before use the mosaic may be covered with a protective layer of cellulose acetate, which can be subsequently dissolved or burnt off.

Title: Devices having conductive tracks at different levels with interconnections therebetween

Filed: 1973-02-28
Abstract: 1468346 Conductive interconnections in iritegrated Circuits MULLARD Ltd 27 Feb 1974 [28 Feb 1973 27 March 1973] 9713/73 and 14590/73 Heading H1K In a device comprising a body with an insulating surface carrying conductive tracks at two levels separated by an insulating layer through an aperture in which a specific pair of tracks on two levels are interconnected, the dimensions of the aperture are such that having regard to the manufacturing tolerances involved in locating the aperture there is no certainty that the aperture will not exceed beyond the edge of the lower level track or a certainty that it will so extend. In a preferred arrangement the substrate is a silicon IGFET integrated circuit structure coated with oxide, the lower level tracks, which are continuous with the IGFET gates and contact the drain and source diffusions, are of doped polycrystalline silicon, the insulating layer of silicon oxide and the upper level tracks of aluminium though Al, Mo, W, and Ti-Pt-Au, Mo-Ti-Au and Ti-Rh-Au laminates are suitable for tracks at one or other level and silicon nitride is an alternative insulator. The apertures are formed by etching through a photoresist mask using a buffered HF solution at 30‹ C., the etching extending slightly into the underlying insulation adjacent the edges of the first level track, though this can be avoided by proper selection of insulation. The apertures, which are generally rectangular, may be wider, of the same width, or slightly narrower than the first level tracks and disposed either centrally of the tracks or offset to avoid the risk of exposing a closely adjacent track at one side. Preferably the arrangement is such that the edges of the aperture lying on the direct current path between the interconnected tracks overlie the lower track to a substantial extent whether the tracks run parallel (Fig. 20a) or normal (Fig. 19a) to each other. Other relative dispositions of interconnected tracks are described with reference to Figs. 25-27 (not shown). The lower level tracks are generally narrower than those at the upper level which are preferably covered with a passivating layer which may bear further levels of interconnections. In some cases the lower track is broadened at the interconnection site, which may involve deviation of an adjacent track to maintain a minimum spacing, and may be of different material there, e.g. an aluminium track may have a molybdenum section to which an upper track of aluminium is connected.
